The gameplay in Random Dice is simple since it's based entirely the most basic Tower Defense mechanics: you have to try to defeat all the enemies in the level before they manage to make their way into your base. For each enemy you destroy, you'll earn coins that you can invest in new and more powerful units that will help you protect your weak points. The merge game mechanics come into play when it comes to planning your defensive strategy: the units that will help you protect your base are dice that you can combine with other dice of the same color and value to increase their attack capabilities.
With each win, you'll have the possibility to unlock new types of dice, each with its own unique and special abilities that you'll have to master in order to win the most challenging battles.
One of the most interesting features in Random Dice is its multiplayer mode. This is where you'll have to compete against players from all over the world to be the last one standing against the incessant enemy hordes.
